Countdown: Release Date, Plot, and Cast – Jensen Ackles Leads Explosive New Prime Video Series
Supernatural and The Boys star Jensen Ackles is set to return to the small screen—this time stepping into the role of LAPD detective Mark Meachum in the upcoming high-stakes action thriller Countdown, arriving on Prime Video June 25. The series, created by Derek Haas—the name behind hits like Chicago Fire, Chicago P.D., and FBI: International—has already generated significant buzz, promising fans a gripping blend of crime, conspiracy, and drama with an all-star cast.
A Prime Video Original Ready for Lift-Off
Prime Video announced Countdown will premiere globally on Wednesday, June 25, starting with a three-episode drop. New episodes will roll out weekly, with the season finale set for September 3. The show will be available in more than 240 countries and territories, ensuring a worldwide audience for this edge-of-your-seat adventure.
Showrunner Derek Haas brings his proven track record with intense, character-driven action to Countdown. “I love making shows that keep you on the edge of your seat with nonstop action, drama, surprises, and suspense,” Haas shared when the show was first announced. Ackles, continuing a fruitful relationship with Prime Video after his breakout turn in The Boys, said, “I simply cannot wait to partner with Derek and the rest of our Countdown family to bring this story to life” (see more about the announcement on the official Prime Video press release).
Countdown Trailer and Viral Buzz
The official trailer teased ticking-clock suspense and explosive setpieces, setting the stage for one of the year’s most anticipated premieres (you can watch the trailer on YouTube). Prime Video also stirred excitement on Instagram with a slick “Reporting for duty” post unveiling Ackles in character as Mark Meachum, piquing the curiosity of fans worldwide as thousands chimed in ahead of the show’s debut.
Plot: A Race Against Time
Countdown launches viewers into the world of Detective Mark Meachum, tasked with unraveling a deadly conspiracy threatening Los Angeles. When a Department of Homeland Security officer is brazenly murdered in broad daylight, Meachum is recruited to a covert task force. Alongside undercover agents from every law enforcement branch, he hunts the killer—only to uncover a plot far more dangerous than anyone expected.
This isn’t just another procedural: creator Derek Haas hints there’s also a tangle of romance woven through the intrigue. He recently teased, “I love the triangle. It’s my favourite shape. And we’re going to have a few of those,” hinting at multiple complex love interests and relationships threading through the narrative.
Ackles, meanwhile, compared his new role to his beloved Supernatural character, Dean Winchester, telling fans to expect echoes of that familiar intensity and humor—but with an entirely new set of challenges and stakes.
